Blatter also considering rule change to clamp down on players faking injury

(CNN) -- Sepp Blatter, the president of world football's governing body FIFA, has exclusively told CNN that he would be in favor of introducing goal line technology into the game if the system used was "accurate and non-complicated."

The statement comes after Blatter, 74, defended a recent decision taken by the International Football Association Board (IFAB) to rule out the use of computer-aids for referees on the basis such devices could not be implemented on a global level.

But in an interview with CNN, the boss of world soccer said the door was still open if the right model could be found: "If we have an absolute and accurate, non-complicated system then I would be in favor.

"But the current systems [on offer], with all respect to the companies [who have developed them], are complicated and not 100 percent accurate," Blatter said.

The Swiss administrator told FIFA's official Web site in March that it was part of the human nature of the sport that even with technology, ultimately, decisions would always rest with referees and that "fans love to debate any given incident."

Blatter revealed that tests had been conducted to analyze whether the use technology was viable, but that major weaknesses with current options had been exposed.

"Speaking about the chip in the ball, which is the most accurate and I can say it works, but it is so complicated. The chip in the ball will create many problems with all manufacturers of the balls.

"[It] is an Adidas system and other manufacturers [need] to have the same rights to have access to this -- this is a fundamental problem.

Blatter added that the "chip in the ball" option also posed significant logistical problems for implementation.

"You cannot use radio waves [to track the ball] because these are interrupted by circumstances, so you have to wire the whole field of play and I think this is too complicated."

The "Hawkeye" system -- whereby strategically-placed television cameras can be used to accurately track the flight of a ball -- also proved problematic when adapted for football, according to Blatter.

"Even the Hawkeye producer has to admit that even with seven cameras, if the ball is in a bunch of players, you cannot see whether the ball is in or out [of the goal]," he added.

Blatter, who has led the governing body since 1998, said he would consider introducing a rule that would force players to spend a minimum of five minutes on the sidelines if they voluntarily left the field through injury.

The law change could help clamp down on players faking injury and wasting time, he said.

"We tried with two minutes in a youth competition. It didn't work because of control, but now we have a fourth and fifth referee [the five-minute rule] could work. It is a good idea."
